这是编译原理里面用来判断输入的东西是是否是符合数学运算公式...

Java写的词法/语法分析器。可生成JAVA语言或者是C++的词法和语法分析器。并可产生语法分析树和对该树进行遍历 -Syntactic and phrase parser in JAVA which can produce JAVA or C

《编译原理实践教程》中的程序作了一些扩展，可以将程序转化成四元式。 本人认为书上的程序极为垃圾！- "Translation Principle Practice Course" the center procedure has made some expansions, may transform the procedure four Yuan types. Myself think in the book procedure extremely trash!

ec++,嵌入式C++编译器，和KEIL结合的很好的，开发过程也比较简单，压缩包中包含说明文档。-ec++, embedded C++ compiler, and KEIL good combination, the development process is also relatively simple, compressed package includes documentation.

对pl0语言的词法分析程序，带分析工具flex。输入一个PL0源程序文件名，即可看到词法统计结果。- To the pl0 language lexical analyaer, brings analysis tool flex. Inputs a PL0 source program filename, namely as worthy of looking at as morphology statistics result.

flex的使用方法-the use of flex

递归下降方法实现的类C语言的语义分析程序-recursive method decreased the Class C language semantic analysis procedures

这个程序是我们的大作业,里面有语法分析,词法分析,四原式等等,里面有具体内容和事例,看看就能明白-this procedure is our largest operation, which has syntax analysis, lexical analysis, the four original type and so on, there are specific details and examples, see we can understand

编译原理课程设计 SLR(1)语法分析!我做的，就是没有运行结果，大家先用着-Course Design Compiler Principle SLR (1) syntax analysis! I do, is not running, we used to first

简单的词法分析器 编译课程综合训练 java语言 -Simple lexical analyzer to compile a comprehensive training course java language

计算机科班学生的词法分析作业，用flex处理生成的VC源程序。- The computer regular professional training student s lexical analysis work, processes the production with flex the VC source program.
